Before use

Inserting the batteries

Do not use damaged batteries.
Make sure that battery polarity is correct.
Change the batteries as soon as the
indicator lights up, and always change the batteries as a pair.

Flip the contact spike forward.

Open the battery compartment.

Insert the batteries.

Close the battery compartment and flip the contact spike back to the closed position.

Switching the laser range meter on or off

CAUTION

Risk of injury! Do not direct the laser beam toward persons.

Never look directly into the source of the laser beam. In the event of direct eye contact, close your eyes and move your head out of the path of the laser beam.

Press the button to switch the laser range meter on.

Press the button and hold it down for 2 seconds to switch the laser range meter off.

Undo

Take a measurement.

Press the button.

The last measurement is undone.

Pressing the
button again takes you directly back to the "Measure distance" function.

Basic settings

Setting the reference

The "Reference" setting influences whether the length of the product is taken into account in measurement. You can select either of two references:
• Top edge of the laser range meter (product length is excluded)
• Bottom edge of the laser range meter (product length is included)
The default setting is
bottom edge of the laser range meter.

Press the button and hold it down for 2 seconds to toggle the reference setting.

The reference is changed.

The reference is reset to the default setting when you switch the device off.

Setting the unit of measure

The unit of measure cycles through the following:

The default unit of measure can vary, depending on the country.

Simultaneously press the and buttons and hold them down for 2 seconds.

The unit of measure is changed.

Repeat step 1 until the unit of measure you want is set.

The setting you select is saved as the new default setting.

Switching the acoustic signal on or off

Simultaneously press the and buttons and hold them down for 2 seconds.

The setting you select is saved as the new default setting.

Using the contact spike

The contact spike makes the laser range meter easier to aim when you are targeting a fixed position.
Measurements from awkward area are easier, for example when you have to measure a diagonal from a corner.

Flip the contact spike open through 90°.

The contact spike can be used as an end stop.

Flip the contact spike open through 180°.

The reference is changed automatically.

Measuring using a target plate

Use the target plate to measure distance under the following unfavorable conditions:

The wall is not sufficiently reflective due to the type of surface.

The target point is not on a surface.

The distance to be measured is too long.

The light conditions are unfavorable (bright sunshine).

When measuring with a target plate, add 2 mm (1/16 in) to the measured distance.

Operation

Overview of the functions

Press the
button to cycle through the main functions.

The "Measure distance" function is selected by default every time the device is switched on.

button after the regular measurement procedure finishes.

Main functions

Measure distance (single measurement)

The laser switches off automatically:
• When a single measurement has been carried out.
• When 90 seconds pass without a measurement being carried out.
• When you switch from a main function directly to the "Measure distance" function.
Short-press the
button to switch the laser on.

Aim the laser at a target point.

Press the button.

Measurement has been completed.

Press the button.

Measurement has been completed.

The following values are shown on the display:
• Measured lengths
• Calculated result

Measure Pythagoras (3-point)

Aim the laser at the first target point.

Press the button.

Aim the laser as the second target point at right angles to the target distance.

You can improve the result by activating the "Min/Max" function.
Press the
button and hold it down for 2 seconds to activate.
Measure the wall vertically until the length has been measured at exactly a right angle.

Press the button.

Aim the laser at the third target point.

Press the button.

Measurement has been completed.

The following values are shown on the display:
• Second length
• Third length
• Calculated result

Using the Layout function

Use the and buttons to set the distance between the layout points.

Press the button to confirm the value.

Take the measurement by passing the laser range meter along the layout baseline.

The following values are shown on the display:
• Distance between the nearest layout point and the wall
• Distance from the nearest layout point

An acoustic signal sounds inside a range of 10 cm from the nearest layout point.
A different acoustic signal sounds when the layout point is reached (display shows
0.000 ).
A minus sign (-) in front of the value indicates that you have to move away from the wall.

Press the button to end measurement.

Special functions

Adding or subtracting measurements

You can use the "Add/Subtract" function to add or subtract the measured values of different functions.

Press the button if you want to add a new measured value or press the button if you want to subtract.

Take another measurement.

If you are using the "Measure distance" function, the result appears automatically. If you are using the Area, Volume or Pythagoras function, you have to press the
button after completing the regular process of measurement.

The following values are shown on the display:
• Previous measurements
• Sum of/difference between measurements

Retrieving or deleting data from data memory

The product can save a maximum of 10 measured values in its data memory.
Every subsequent measurement automatically deletes the oldest measured value.

Press the button.

The 10 most recent measured values are displayed.

Use the or buttons to browse through the measured values in memory.

Alternatively, repeatedly press the
button.

Simultaneously press the and buttons and hold them down for 2 seconds to delete the measured values saved in the device's data memory.

All measured values are deleted from the device's data memory.

Taking a continuous measurement (min/max)

The following values are shown on the display:
• Maximum value
• Minimum value
• Current measured value

Press the button to stop measuring.

The following values are shown on the display:
• Maximum value
• Minimum value
• Last measured value

Taking delayed measurement (timer function)

Delayed measurement (timer function) enables precision measurements over long distances.
Measurement takes place automatically when a countdown time out. This rules out slight movement of the laser range meter such as can occur when a button is pressed, for example.
The timer function can be used in all the main functions.
The default is 5 seconds.

Press the button and hold it down for 2 seconds.

Use the and buttons to set the timer.

Press the button to confirm the value.

The countdown starts.
